The Cologne-based European Aviation Safety Agency said Thursday that "airlines have expressed a need for a consolidated picture of the safety/security situation" and have "vastly different resources available to them."

EASA is urging EU nations to establish national systems for addressing risks to civil aviation over combat zones, which EASA would then distribute. It says intelligence agencies should contribute information, as well as the airlines themselves.

The proposal is being given to the Dutch presidency of the European Council.

The Dutch Safety Board said in its final report that Flight MH17 was destroyed by a Soviet-designed missile.
